Genes affected
NF1 (HGNC:7765): (neurofibromin 1) This gene product appears to function as a negative regulator of the ras signal transduction pathway. Mutations in this gene have been linked to neurofibromatosis type 1, juvenile myelomonocytic leukemia and Watson syndrome. The mRNA for this gene is subject to RNA editing (CGA>UGA->Arg1306Term) resulting in premature translation termination. Alternatively spliced transcript variants encoding different isoforms have also been described for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.52).
BP6
Variant 17-31201150-A-G is Benign according to our data. Variant chr17-31201150-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 237511.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.35 with no splicing effect.
BS2
High AC in GnomAdExome4 at 18 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
